Single-Family Market Reports

The reports

Publishing standards

• Every statistic carries four labels: source, date pulled, geography, and methodology.
• No fabricated or estimated MLS figures. If data hasn’t been pulled, the cell stays empty.
• Single-family homes only, reported separately from condos, TICs, and multi-unit properties.
• Geography by MLS neighborhood or incorporated city, never by ZIP code alone.
• Median first, with average shown alongside; monthly figures paired with trailing three-month figures.
• Opinion is labeled. Observations are clearly marked as Thomas’s interpretation.
• Corrections: if a published figure is revised, the change and the date are noted on the report.

Publishing schedule

1. By the 5th business day of each month: export prior-month data from each MLS using the saved filters.
2. Check: remove duplicates and obvious data errors; note any exclusion.
3. Publish: update tables, the “last updated” date, and dateModified in the page’s structured data; add observations.
4. Archive: keep each month’s figures so year-over-year comparisons remain verifiable.
